Fire doors are required to provide two main functions:
a) To maintain any compartmentation of buildings, which has been introduced to limit the size and spread of fire in order to control the perceived risk
b) To allow access to protected escape routes, both vertically and horizontally, without any loss of fire resistance, and limit smoke movement in the structure forming these routes, i.e. protected corridors and protected shafts.
BS 8214 gives recommendations for the specification, installation and maintenance of fire doors. The recommendations are applicable only to hinged or pivoted pedestrian doorsets, door assemblies, or door leaves of any material, fitted into frames of any material.
BS 8214 is applicable only to doors that are designed to provide fire resistance ratings of up to and including 2 h when tested in accordance with BS 476-22 or BS EN 1634-1.
This British Standard is applicable only to the fire performance of the doors and doorsets. It does not cover security, ergonomic factors, functional performance other than with respect to fire resistance, or safety of glazing.
